Abstract: ABSTRACT      A hydraulic fluid circuit system is provided for use in a vehicle  and  having  a  priority  and  a  second  fluid  circuit therein.   A variable displacement pump is  the primary fluid source for the priority circuit, and a fixed displacement pump is the primary fluid source for the second fluid circuit.  A demand valve  responsive  to  differential  fluid  pressure  between  the priority circuit and the output of the variable displacement pump selectively switches increasing amounts of output from the fixed displacement pump into the priority circuit in proportion to the output  of the  variable  displacement pump.   The  demand valve includes a three positioned spool valve.   The priority circuit may include a hydraulic steering system,  and the second fluid circuit may include an implement or accessory circuit.

Abstract: ABSTRACT OF THE DISCLOSURE A game cup and method wherein the cup comprises a waxed paper cup having a rolled lip with game information printed inside of the rolled lip in a game information area thereof.  A semi-circular snap-out section, defined by a series of spaced-apart slits, is located below the game information area of the lip but spaced therefrom.  To reveal the printed game information, a finger is pushed in against the snap-out section to break it away from the remainder of the cup sidewall.  The snap-out section is then pulled upwardly tearing a portion of the sidewall away up to the lip, and then the snap-out section and torn portion are moved or rotated around the rolled lip so as to unroll the rolled lip and reveal the printed game information.

Abstract: CONNECTING APPARATUS FOR AN INFORMATION PROCESSING SYSTEM     ABSTRACT OF THE DISCLOSURE         Apparatus for connecting at least one recovery station to preselected ones of plural recorders in an information processing system to recover information jobs from those recorders.  Indications of those preselected recorders to which the recovery station is to be connected are stored.  Depending upon the criteria on which the recovery station is to be connected to the recorders (e. g. backlog of information jobs awaiting recovery or predetermined sequence), the appropriate one of the recorders is selected and connected to the recovery station. upon completing the recovery of information jobs from the connected recorder, the next of the preselected recorders is selected in accordance with the aforementioned criteria.         Although the recovery station may be connected to recover all of the information jobs in a recorder, apparatus for monitoring and storing data related to those information jobs, including the status thereof, indicates that only the information job which is in the process of recovery is "assigned" to that recovery station, while the remaining jobs which await recovery merely are "ready" to be assigned.

Abstract: ABSTRACT           A magnetic tachometer for generating a signal as a function of the velocity of a transducer positioning arm in a disk drive.  The tachometer is formed by a pair of fixed parallel coils separated by a distance sufficient to allow a magnet, attached to a counterbalance portion of the rotary positioning arm to move therebetween and thus to generate a voltage as a function of the velocity of the magnet.  The coils are each wound over a thin armature member which is saturated by the magnet's magnetic field and they are differentially coupled to produce common mode rejec-tion.

Abstract: A LOAD CONTROL SYSTEM Abstract of the Disclosure A load control system is disclosed for preventing the uncontrolled lowering of a load should a line failure occur in a hydraulic system.  The system is designed to be used with a hydraulic cylinder having a movable piston therein which divides the cylinder into a head end and a rod end.  Attached to the piston and extending out of the hydraulic cylinder is a piston rod which has a load secured to its free end.  The load control system includes a source of pressurized fluid, the flow of which is selectively controlled to the hydraulic cylinder by a control valve.  Positioned between the control valve and the head and rod ends of the hydraulic cylinder, respectively, are first and second valves each of which is normally biased towards a closed position by a common pressure.  The first and second valves are urged toward an open position by fluid pressure taken between the control valve and the first valve and are movable by this fluid pressure in a proportional manner with the second valve being opened first.  The second valve is also physically mounted directly to the hydraulic cylinder such that if a line breakage occurs, the load will still be unable to drop.

Abstract: ABSTRACT OF THE DISCLOSURE         A chlorine injector for treatment of effluent, comprising apparatus which provides two separate vacuum forces that supplement each other to create sufficient vacuum force to draw chlorine from a chlorine tank and inject it into a sewage effluent tank for treatment of the effluent therein.  The apparatus includes a water chamber positioned above the surface of the effluent, an airlift tube extending from the water chamber having its intake end submerged in the effluent and its discharge end inside of the water chamber at the upper portion thereof, an overflow return pipe extending from the water chamber to return excess effluent to the tank, and the chlorine injection assembly having the double vacuum means comprising a first eductor nozzle leading from the bottom of the water chamber to discharge into a second induction nozzle having a flared intake end, creating a first vacuum at this point by the venturi effect.  Chlorine is introduced at this point by an inlet port opening in the side wall of the flared end region of the second nozzle, a chlorine supply hose being connected to the inlet port and leading to the chlorine supply tank.  The second nozzle is connected to an injection tube which provides the second vacuum by virtue of a "hanging column of water" achieved by positioning the second nozzle an appropriate distance above the surface of the effluent, such as 40 inches or more, then providing the injection tube with sufficient length for its discharge end to be below the surface of the effluent, nd proportioning the diameter of the second nozzle in relation to the diameter of the injection tube whereby a continuous column of water extends from the second nozzle to the discharge end of the injection tube while the treatment apparatus is in operation.  Such proportion may for example be a 1/2 inch diameter far the nozzle and a 3/4 inch diameter for the injection tube.  The injection tube discharges into a coaxial dispersion tube of larger diameter whose discharge end is below the discharge end of the injection tube.  Effluent is lifted from the effluent tank to the water chamber through the airlift tube by a pressurized air supply, connected near the lower end of the airlift tube submerged in the effluent.  The effluent water then flows downward from the water tank through the eductor and induction nozzles and the injection tube, then the dispersion tube and back into the effluent tank, creating the two vacuums as it flows through this assembly of nozzles and tubes, drawing the chlorine in as it flows past the chlorine intake port and mixing the chlorine with the effluent water as it flows into and through the injection and dispersion tubes.

Abstract: SYSTEM FOR TRANSFERRING DRY FLOWABLE MATERIAL          Abstract Of The Disclosure A system for transferring dry flowable material includes a substantially closed vessel having an inlet and a discharge end.  A cycle valve and venturi are arranged between a source of fluid pressure and the vessel such that the cycle valve may be selectively actuated to pass pressurized fluid directly to the vessel or through the venturi,  A suction line interconnects the vessel to the throat section of the venturi such that passage of fluid flow through the venturi establishes a suction within the vessel.  A pressure responsive control switch has direct communication with the throat of the venturi so as to detect the fluid pressure therein and is operative in response to a predetermined pressure within the venturi to condition the cycle valve for effecting a suction within the vessel sufficient to substantially fill the vessel with material, after which material is sucked into the venturi to cause a change in fluid pressure therein such that the pressure responsive control switch causes the cycle valve to pressurize the vessel and effect discharge of material therefrom.  The cycle valve and pressure responsive control switch effect automatic cyclical fill and discharge of the vessel.
